What will be the result for each qualitative test if the intact casein contains the following peptide chain: Ala-Arg-Asp-Glu-Gly-His-Ile-Leu-Lys-Met-Phe-Pro-Ser-Thr-Trp-Tyr-Val What will be the result for each qualitative test if hydrolysis of casein results to the following: Acid hydrolysis = Total hydrolysis of peptide bonds; Trp is destroyed and converted to humin (black pigment); Thr and Ser are destroyed; Asn and GlIn are converted to Asp and Glu . Basic hydrolysis = Total hydrolysis of peptide bonds; promotes racemization; Thr and Cys are lost; Arg is destroyed

What will be the result for each qualitative test if the intact casein contains the following
peptide chain:
Ala-Arg-Asp-Glu-Gly-His-Ile-Leu-Lys-Met-Phe-Pro-Ser-Thr-Trp-Tyr-Val
What will be the result for each qualitative test if hydrolysis of casein results to the following:
Acid hydrolysis = Total hydrolysis of peptide bonds; Trp is destroyed and converted to humin
(black pigment); Thr and Ser are destroyed; Asn and Gln are converted to Asp
and Glu
Basic hydrolysis = Total hydrolysis of peptide bonds; promotes racemization; Thr and Cys are lost;
Arg is destroyed
